SEAT-CUSHION.

SPECIFICATION forming part of Letters Patent N0. 778,239, dated December 27, 1904.

' Application filed May 27,1904. Serial No. 210,034.

To all whom it may concern.-

Be it known that I, HENRY S. HALE, of the city and county of Philadelphia and State of Pennsylvania,have invented an Improvement in Seat-Cushions, of which the following is a specification. Y

My invention has reference to seat-cushions; and it consists of certain improvements which are fully set forth in the following specifica tion and shown in the accompanying drawings, which form a part thereof.

The object of my invention is to provide a convenient and inexpensive means for securing the upholstery upon sheet-metal boxframes of seat-cushions.

In carrying out my invention I provide the lower or back flanges of the box-frame with clamping angle-strips, between which and the flange the edge of the upholstery is clamped. The upholstery is stretched over the box-frame and bent under the flange and around its free edge, and it is clamped at this latter place by the angle-strips, which are drawn tightly into place by bolts, as will be better understood by reference to the drawings, in which Figure 1 is a perspective View of a seatcushion embodying my invention with a portion broken away to show the internal structure. Fig. 2 is a cross-section of a portion of same on line 2 2 of Fig. 3, and Fig. 3 is an inverted plan view of a portion of the seat cushion.

A is the box-frame, of sheet metal, and has the upper flange B and the lower flange C, which may be bent up or beaded on its edge, as at C. i Y

D is one of the flat steel spring-bands which support the upholstery and is riveted at its enocls to the upper portion of the box-frame A at F is one of the sheet-metal slats and is ribbed, as shown, for strength. The ends of these slats are bent downward and rest upon the upper surface of the lower flange and may be riveted to it. Coil sprin'gs E are supported upon the slats F and sustain the springplates D.

The upholstery G is stretched over the seat and bent under the lower flange C of the boxframe, and the lower edge is turned up, as at g, against the edge of the flange. The upholstery is preferably of woven ratan and in a moistened condition when being applied. The edges of the ratan or other upholstery are then clamped in position by the angle plates or strips H, which are drawn up tightly into position by the bolts I. The short arms it of these angle-plates extend upward and hold the edge 9 of the upholstery in the position shown, and when it dries it will be found to be most rigidly secured in place. The extended flat surfaces of the plates or strips H give protection to the under part of the upholstery and prevent injury thereto.

The bend g in the upholstery maybe omitted, if desired, and the edge Will in this case be shielded by the upwardly-extending part it of the clamping-plate H, and said upwardly-extending part will also prevent the clampingplate from shifting its position laterally and outward.

While I prefer the construction shown, I do not confine myself to the exact details, as these may be modified in various ways without departing from the spirit of the invention.

Having now described my invention, what I claim asnew, and desire to secure by Letters Patent, is i 1. In a seat-cushion, the combination of a box-frame having lower flanges, with upholstery extending over the box-frame and having its edges folded under the flanges and upward against the inner edges thereof, clamp ing-plates L-shaped in cross-section fitted against the under side of the upholstery and clamping it against the under surface and inner edges of the flanges of the box-frame, and clamping-bolts for clamping said clampingplates in position.

2. In a seat-cushion, the combination of a sheet-metal box-frame having upper flanges and lower flanges the lower being beaded upon their inneredges, spring-plates secured to the box-frame and extending over its upper portion, cross-slats extending across the lower part of the box-frame, springs supported upon said slats and sustaining the springplates, upholstery extending over the boxframe and springs and having its edges folded under the flanges and upward against the inner edges thereof, clamping-plates L-shaped in cross-section fitted against the under side of the upholstery and clamping it against the under surface and inner edges of the flanges of the box-frame, and clamping-bolts for clamping the said clamping-plates in position.

3. In a seat-cushion, the combination of a sheet-metal box-frame having upper and lower flanges, spring structures supported upon the lower flanges of the box-frame, upholstery extending over the spring structures and upper flanges and having its edges folded under the lower flanges of the box-frame, clampingplates secured to the under side of the boxframe and upon the upholstery to clamp it and having a projecting part b extending upward adjacent to the inner edge of the lower flange, and clamping devices extending through the clamping-plates upholstery and flange of the box-framefor securing the clamping-plates in position.

4. In a seat-cushion, the combination of a box frame having fiat under surfaces and spring structures supported by the box-frame, upholstery extending over the spring structures and having its lower edges folded under -the box-frame adjacent to the under surface thereof, and means extending through the clamping-plate and upholstery for clamping them to the box-frame.

5. In a seat-cushion, the combination of a sheet-metal box-frame having a lower flange C curved into a rounded edge 0, upholstery extending over the box-frame and having its edges folded under the flange C and upward against the rounded edge 0, and a clampingplate extending over the upholstery below the flange and upward adjacent to the rounded edge C to clamp and shield the edge of the upholstery.

In testimony of which invention I hereunto set my hand.

HENRY S. HALE.
